 For convenience, QIDI provides version-specific packaged files. Please download the necessary compressed package file prefixed with "PLUS4." Select the appropriate branch for download, with each branch name reflecting the corresponding version.
 
-## V1.4.3 Update Content
+## V1.6.0 Update Content
 
 **Note:** After updating, the Klipper configuration file will be replaced. The previous configuration file will be backed up as `printer_{datetime}.cfg`, printer recalibration will be required.
 
-1.Optimize the execution logic of chamber heating.
+1. Added network testing functionality.
+2. Added support for AX300 and AX600 Wi-Fi adapters.
+3. Optimized chamber heating logic: chamber heating starts only when the heated bed reaches the specified temperature.
+4. Added temperature limits and reminders (chamber, heated bed, nozzle) on the Fluidd page.
+5. Fixed an issue where disconnection caused online updates to crash.
+6. Fixed the problem of losing settings after rebooting following a language switch.
+7. Enhanced support for LAN mode.

+
+## The online update version will be uploaded later. If you have already updated this version earlier, please ignore the online update prompt.
